Received 05/09/2012 SAFETY BARRICADE AND/OR GUARDING SYSTEM
FIELD OF THE INVENTION
The present invention relates to a mounting clip and a safety barricade and/or machine guarding system using that mounting clip. More specifically, the present invention can be used as part of a safety barricade system that is installed around the perimeter of a building or structure and used during or after construction in order to prevent objects from falling from the building or structure. The present invention can also be used in machine guarding applications.
Scaffolding is required in many construction scenarios: Scaffolding significantly reduces the risk of workers falling from height. However, scaffolding usually consists of interconnected = horizontal and vertical rails, and there is still significant spacing between the scaffold rails.
Accordingly, there are many instances where tools or building materials fall to a lower level or the ground, which endangers works on the site.
Shade cloth is used on some construction sites to reduce direct sunlight, and reduce the likelihood of objects falling or being blown from the site by high winds. A
disadvantage with --existing shade cloth is that it is often time consuming to install, and may not be sufficiently =
strong to withstand forces generated by some falling objects.
Another problem with existing shade cloth and other temporary construction screening is that they can be difficult and/or time consuming to install on non linear, curved surfaces, or areas and surfaces having abnormal geometry.
DISCUSSION OF THE PRIOR ART
The Thaler Patent Application Publication (U.S. Pub. No. 24 2006/0180390) discloses a roof fall protection apparatus that comprises several components that can be easily assembled and disassembled on site and that are adaptable to various building geometries. However, the apparatus requires at least two support members in order to assemble the apparatus thereon, and does not rely upon existing structures.
The Preston Patent (U.S. Patent No. 4,129,197) discloses a safety-catch scaffolding system adaptable to the progressive growth of a building during construction having a series of spaced uprights, each having a plurality of vertically disposed slots for the sliding engagement of the edges of a plurality of frames.

The mesh panel 101 may be manufactured in a variety of sizes. In the embodiment shown in the drawings, the mesh panel 101 includes a grid matrix pattern therein, which prevents objects larger than the spacing of the matrix from falling off of an elevated surface or structure when installed. The mesh panel 101 is light weight, approximately 2.6 Kg per metre attached. The mesh panel 101 is manufactured in modular plastic components consisting of, Geloy HRA222F/HRA170D and PVCU.
The clips 102 are provided in two different mounting configurations. A tubular clip 105 as depicted in Fig. 3 is used to secure the mesh panel 101 to a tubular element such as a scaffold rail or post. In contrast, a kick rail clip 104 is depicted in Fig. 4 and used for securing a mesh panel 101 to a flange or other edge such as a kick rail. By using a.
combination of tubular clips 105 and rail clips 104, the mesh panel 101 can be secured to a wide range of fixed structural elements on a construction site.
Referring to Fig. 4, the kick rail clip 104 includes a first engagement formation in the form of a plurality of cavities or slots 104A that are generally parallel with one another. The slots 104A each include angled teeth 104B therein. The angled teeth 104B are presented at an angle such that upon insertion of a panel or board-like object 130 therein, the angled teeth 104B will engage said object therein, and inhibit removal of the object from the respective slot 104A.
As shown in Fig. 1, the kick rail clip 104 is ideally used to grip onto a rail or other such object 130, such as a kick plate, but may be secured to any other plate like structure.
The kick rail clip 104 includes one or more second engagement formations defined by holes 104C, which are located to enable attachment of an eccentric pin joiner 106 thereon. The eccentric pin joiner 106 includes a third engagement formation defined by a first projection 106A that extends perpendicularly with respect to the body of the eccentric pin joiner 106.
The eccentric pin joiner 106 also includes a fourth engagement formation defined by second projection 106B, which extends perpendicularly with respect to the body of the eccentric pin joiner 106, and more particularly, the second projection 106B extends in an opposing direction with respect to the first projection 106A. The first projection 106A
is generally parallel with respect to the second projection 106B. The first projection 106A
is offset with respect to the second projection 106B, such that the first projection 106A is not aligned with AMENDED SHEET

7 Received 05/09/2012 the second projection 106B. The orientations of the two projections 106A and 106B is depicted in the cross sectional view of FIG. 9. The body of the eccentric pin joiner 106 has generally oval shaped profile.
By rotating the eccentric pin joiner 106 about the first projection 106A, the second projection 106B translates around a circle, which is generally coplanar with the mesh panel 101.
Both the first projection 106A and the second projection 106B each include a circumferentially extending flange 1060 for securement with the holes 1040 of the kick rail clip 104 or with a stopper element, depicted in the form of a mesh clip button 107. The flanges 1060 are defined by one or more frustoconical portions, or a flared, barbed head located at or near the end of the projections 106A, 106B. The flanges 106C
enable the two parts to snap together, but inhibit subsequent separation of the two parts.
The mesh clip button 107 is a generally circular disc having a fifth engagement formation defined by a centrally formed hole 107A, which is used to attach the mesh clip button 107 onto either the first projection 106A or the second projection 106B of the eccentric pin joiner 106.
The mesh clip button 107 and the eccentric pin joiner 106 are used to sandwich and secure a portion of a mesh panel 101 there between, and to attach to the clip 102.
Referring to Fig. 3, the tubular clip 105 is designed to secure the mesh panel 101 against a tubular surface 131, such as a handrail (see FIGS. 1 and 8-10). The tubular clip 105 has a generally clevis shaped body including a first engagement formation, depicted here as two arms 105A. The two arms 105A mirror one another, and form an opening 105B into which a tubular surface 131 such as a handrail is inserted when in use. It shall be noted that the tubular clip 105 and the cylindrical opening 105B may be scaled up or down to accommodate differently sized tubular surfaces 131.
Both of the arms 105A include a hole 105C that enables a pin 105D to be inserted there between and enclose the tubular surface 131 therein. The pin 1050 includes circular flanges 105E that are analogous to the circular flanges 1060 of the first projection 106A and the second projection 106B of the eccentric pin joiner 106. The pin 1050 includes a shoulder 105F, which works with the circular flanges 105E to secure the pin 105D to the two arms 105A.

As described earlier, the barricade system 100 may include joiner assemblies 103 to secure adjacent sections of the mesh panels 101 together. Referring to FIGS. 2 and 5, a vertical joiner assembly 110 includes two cavities or channels 111 that extend in generally opposing directions relative to one another. The vertical joiner assembly 110 is of an undefined length, and in which the two cavities 111 span said undefined length. The cavities 111 include angled teeth 112 therein, which are oriented at an angle in order to grab and secure an edge 101A of the mesh panel 101 therein. The teeth 112 work in a manner consistent with the angled teeth 104B of the kick rail clip 104 described above. The vertical joiner assembly 110 includes a cap 113 that clips onto an end of the vertical joiner assembly 110 so as to enclose the side profiled openings of the cavities 111.
Referring to FIG. 6, the invention 1-00 may employ the use of a corner joiner assembly 115, which is of an undefined length and features a 90-degree angle 116 that is formed between two cavities 117. The cavities 117 feature the angled teeth 112 described above in regards to the vertical joiner assembly 110. The corner joiner assembly 115 includes a cap 118, which works in the same manner as the cap 113 described above.
Referring to FIG. 7, the invention 100 may employ the use of an obtuse joiner assembly 120, which is of an undefined length and features an obtuse angle 121 that is formed between two cavities 122. The cavities 122 feature the angled teeth 112 described above in regards to the vertical joiner assembly 110. The obtuse joiner assembly 120 includes a cap 123, which works in the same manner as the cap 113 described above.
The joiner assemblies 103 (the vertical joiner assembly 110, the corner joiner assembly 115, and the obtuse joiner assembly 120) all provide the same function which is to secure adjacent sections of the mesh panels 101 together, but differ with respect to one another in the angles formed between the respective cavities. It will be appreciated that the joiner assembly 103 may be made to accommodate other angles, including an acute angle less than 90 degrees.

With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the barricade system 100, to include variations in size, materials, shape, form, function, and the manner of operation, assembiy and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the invention 100.
The barricade system 100 includes at least one mesh panel 101 that is secured against an existing surface, object, or structure via a plurality of the clips 102. The safety barricade system 100 is designed to adaptively attach onto a building or structure in a temporary or permanent basis, and prevent objects from falling there from. The safety barricade system 100 includes tools that remove the clips 102 after use as well as joiner assemblies that abut adjacent sections of mesh panels 101 at varying angles. The clips 102 each include an eccentric pin joiner and mesh clip button that attach to one another as well as onto the respective clip 102, and sandwich the mesh panel there between so as to secure the mesh panel 101 to the respective clip 102.
The operation of the barricade system 100 will now be described. When a mesh panel 101 is to be mounted on a construction site or other location, a plurality of tubular clips 105 or kick rail clips 104 are initially located as required and fastened to kick rails or tubes as described above.
The eccentric pin joiner 106 is placed against the tubular clips 105 and kick rail clips 104, and the eccentric pin joiner 106 is snapped into engagement such that the first projection 106A positively engages with one of the holes 104C, 105G. The mesh panel 101 is then placed against the eccentric pin joiners 106. If the apertures on the mesh panel 101 do not line up with the second projections 106B, one or more of the eccentric pin joiners 106 may be manually rotated. On account of the eccentric nature of the eccentric pin joiner 106, by rotating the eccentric pin joiner 106 about the first projection 106A, the location of the second projection 106B translates around an arc. When a suitable position is reached such that the second projection 106B lines up with openings in the matrix of the mesh screen 101, the mesh screen 101 is pushed into place, and the clip button 107 is snapped into engagement with the second projections 106B. The length and width of the apertures in the mesh panel 101 is smaller than the diameter of the clip button 107, so the mesh panel 101 is unable to be unintentionally removed.

However, it will be appreciated that the first projection 106A and clip button 107 may 5 be connected with a set screw, grub screw or other fastener.
Advantageously, the barricade system 100 includes a plurality of joiner assemblies that enable abutting sections of mesh panels to be secured to one another at a plurality of angles.
The barricade system 100 provides a removal tool that aids in removing the clips 102 from a tubular surface.
Advantageously, the barricade system can be used on platforms, stairways, stair risers, scaffolding, machine guarding as well as barricading and many more applications.
Advantageously, the barricade system is fast and easy to install, minimising disruptions onsite. There is no onsite design or fabrication required.
Advantageously, the barricade system is non heat conductive, anti-static, anti-corrosive, fire resistant, impact resistant, chemical resistant, UV Stabilised, non-conductive, light weight (approx 2.6 Kg per metre attached).
Advantageously the barricade system is reusable, and suits permanent or temporary installations.
Advantageously the safety barricade provides eccentric pin joiners and mesh clip buttons that sandwich a small portion of the mesh panel and also secure the mesh panel to the respective uniquely defined clip.
Although the invention has been described with reference to specific examples, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms.
